Filling the Gap between Users and Objects: A Multichannel Interactive Environment

The design and the implementation of software for mobile computers and for pervasive computing environments entail several issues and lead to new requirements. Applications must handle at run-time the heterogeneity of delivery contexts in terms of devices features, network bandwidth, input and output modalities, operating systems, and so forth. In this paper, we propose a practical approach for enabling platform independent application development and on-the-fly generation of user interfaces based on object introspection and device adaptation
